Description
The ALICE experiment at the CERN LHC is being upgraded during the ongoing second long shutdown of the LHC (2019-21) to enhance the vertexing, tracking and readout capabilities. This would improve upon the present physics measurements, provide insights into new measurements and to fully exploit the scientific potential of the LHC with heavy ions at high luminosity. In Runs 3 and 4 from 2021, ALICE should be able to handle an interaction rate of 50kHz. To cope with these higher rates, the ALICE Muon Tracking Chambers (MCH) would require an upgrade to the front-end electronics and the entire readout chain. The MCH detector, based on Cathode Pad Chambers, would remain the same. The new front-end electronics is based on a new ASIC (SAMPA). The readout chain consists of the Dual Sampa card hosting SAMPA, new front-end links, a new concentrator card (SOLAR) and the Common Readout Unit. In this presentation we will discuss the concept, features and performance of the MCH upgrade system.
